I'm using CLISP on Windows 7, and simply wanted to format the entries in REPL by using tabs to indent. Of course, I got something different from what I expected. This is a tutoring project, so I'm trying to make it as easy as possible.

I may just move to Racket, or I may actually implement emacs on Windows, but I'm just trying to eliminate admin overhead.

As for output; I think I'll just direct my student to Project Euler and see what that does.

The only other way I know with CLISP is using the readline library (if CLISP is compiled with readline, what it usually is) and setting up your own readline keybindings and editor functions, what is a multiple pain than using Emacs and SLIME:
